Photovoltaic panel installation on the roof of a flat factory building

As factories are energy-intensive buildings, installing a solar PV system on the roof of a factory ensures free power can be generated to run everything underneath it. While reducing energy costs, a solar PV installation has the added benefit of demonstrating Corporate Social Responsibility thanks to its environmental credentials.

Designing and installing a PV system on a flat roof requires careful planning and the adoption of innovative solutions to ensure optimal performance and durability. By using high-quality materials, such as GB Solar's precast concrete PV ballasts, and following best engineering practices, a safe, stable, and efficient PV system can be built.

Thanks to recent advances in solar technology and the tax benefits offered in many countries, more and more building owners are opting to install photovoltaic systems on their roofs. However, designing and installing a PV system on a flat roof requires careful planning and a thorough knowledge of engineering best practices.

There are two primary mounting methods for PV systems on commercial building roofs: Ballasted Racking – Uses heavy weights, typically concrete blocks, to anchor PV systems on a flat roof. Some hybrid-ballasted systems use a combination of ballast and roof penetrating anchors to fasten the system to the roof.

In addition, flat roofs allow for greater flexibility in panel arrangement, enabling optimization of orientation and tilt to maximize sunlight absorption. The choice of materials and support structures is crucial to ensure the stability and durability of your PV system.
